How to take travel photos with long depth of field using Canon 60D SLR 13--135 focal length

Using Canon 60D to take depth-of-field photos can be taken in AV mode.

1. Canon AV mode is aperture-priority automatic exposure. Changing the aperture setting will change the background image effect.

2. If the aperture is set to be larger, f/4, the depth of field will be shallower, and the focal length will be shallower, and the scene behind the focal length will become blurry on the day surface. On the contrary, the finer the aperture setting, the deeper the depth of field, the focal length, and the clearer the day surface will be. clear.

3. If you simply narrow the aperture, the amount of incident light will be half. To take a photo with the same brightness in the daytime, you must double the shutter speed (exposure time). Comments Selecting automatic exposure can make the brightness of the daylight surface just right, and the camera will automatically set the shutter speed.

4. After adjusting the mode dial to AV, then adjust the electronic main dial to change the aperture setting value. The electronic main dial is located behind the shutter button. There are pits on the left and right sides of the circular straight body. That's the rotary knob.
